Genes affected

TH (HGNC:11782): (tyrosine hydroxylase) The protein encoded by this gene is involved in the conversion of tyrosine to dopamine. It is the rate-limiting enzyme in the synthesis of catecholamines, hence plays a key role in the physiology of adrenergic neurons. Mutations in this gene have been associated with autosomal recessive Segawa syndrome. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.

Autosomal recessive DOPA responsive dystonia

Uncertain:3

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jun 22, 2022	This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 465 of the TH protein (p.Ser465Cys). This variant is present in population databases (rs767211543, gnomAD 0.004%). This missense change has been observed in individual(s) with dystonia (PMID: 28186668). ClinVar contains an entry for this variant (Variation ID: 554418). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. This variant disrupts the p.Ser465 amino acid residue in TH. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 33233562). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
